Contact Music Direct, ask about the "Sumiko Analogue Survival Kit"
It consists of a vinyl/plastic transparent arm wrap (about 3/8" wide) that is stretched before wrapping and then constricts itself (yes like a Boa) around your arm tube, will kill arm tube vibrations and ringing, made very noticible improvement on my Graham standard wand, I later upgraded to the ceramic.
It also comes with a VERY thin gauz like 12" round vinyl placed between platter and LP (NOT A MAT!!) It is ULTRA THIN transparent weave vinyl, about as thick as a single ply sheet of toilet paper, Just like your platter and LP, a perfect interface (fills in the gaps between platter and LP) to drain vibrations out of the LP. IT is VERY VERY effective.
